Inventor: NAUMANN FRITZ DIPL-ING
IPC: F16H61/18
Filed: 1969-09-12
Abstract: A five-speed change-speed transmission, especially for sports-type vehicles, in which the shifting channels for fourth and fifth speed are disposed in one plane of rotation of the shifting shaft, the shifting channels for the second and third speeds are disposed in a second plane of rotation of the shifting shaft, the shifting channel for the first speed is disposed in a third plane of rotation adjacent to the second plane of rotation and the shifting channel for a reverse speed is disposed in a fourth plane of rotation of the shifting shaft, offset to the third plane of rotation in the axial direction of the shifting shaft; during a shifting down operation, the shifting shaft is normally prevented from reaching the third or fourth plane of rotation by a locking device which can be rendered ineffectual by operation of a push-button or the like at the shifting lever.

Title: Jacquard device for closed shed partic for - high - speed looms
Inventor: PIERRE LOUCHEUR JEAN
IPC: D03C3/06
Filed: 1969-11-05
Abstract: A heald is attached by a hook to a knife above the comber board, both the latter and the knife performing equal movement vertically, but in the opposite direction. A recorder consists of a resilient hook connected via a guide to the heald hook, the resilient hook interacting with a second knife and moveing at the required moment under the action of the second knife, thus exercising a pull on the guide and heald hook. The latter is then withdrawn from the radius of action of the knife above the comber board.

Patent DE-2011528-A1 (DE)
Title: In vitro study of influence of active groups - of cancer
IPC: C12Q1/00
Filed: 1970-03-07
Abstract: The method provides a rapid and certain method of measuring the carcinogenic activity of lack of B-vitamins and of their anti-carcinogenic effect. It is based on the fact that while both respiration and fermentation break down carbohydrates to pyruvic acid, thereafter fermentation hydrogenates this to lactic acid while respiration oxidises it to acetic acid. The respiration and fermentation of isolated 10-day chick embryo cells prepd. with Trypsin is measured in the absence and presence of vitamin B1. A culture of the embryonal cells is subcultured and the respiration and fermentation measured in the presence and absence of vitamin B1 by measuring the H pressure at intervals by the manometric method. From the results the amt. of lactic acid formed is calcd. Addn. of 0.25 mu g/ml. vitamin B1 can reduce the amt. from 36.5 to 93.1 mm3.
Patent DE-2015442-A1 (DE)

Abstract: Reaction furnace tubes with integral internal heat exchanger, partic. for steam reforming of hydrocarbons in presence of catalysts at >=800 degrees C and >=30 psig e.g. prodn. of H2, cools emerging gas to temps. that make unnecessary currently unavoidable use of high grade alloy steels and costly mfg. methods, while utilising reaction heat so extracted for steam raising, or superheating, or for pre-heating gas, etc. as desired. Heat exchanger has quick acting attachment, e.g. flange to reaction tube cool end, and fins at distance from inner reaction wall tube reaching from above emerging gas pigtail outlet to catalyst. Heat exchanger top may form catalyst support. It may be designed for simultaneous passage of two or more cooling media with in- and outlets to its lower end, the incoming medium being carried to its top through a concentric tube, the outgoing medium leaving from close to its bottom. To offset effect of possible soiling on its heat transmission coefficient, it may be in several separately controlled sections, which may bring on steam as needed and it may be partially provided with removable thermal insulation. Its wall facing the gas resulting from thermal decomposition may carry refractory protection.
Patent DE-2139309-A1 (DE)
Title: Magnetic casting - esp of spheroidal graphite cast iron
IPC: B22C11/00
Filed: 1971-08-05
Abstract: Precision high-quality casting, esp. of spheroidal graphite cast iron, is achieved by surrounding mould of non-magnetic refractory material with supporting particulate magnetic material which holds mould in position. The mould with supporting material is exposed to a magnetic field which is maintained during casting and during subsequent solidication, to magnetise supporting material.

Patent DE-2145759-A1 (DE)
Title: Bearing material flange sleeves - made from cylindrical blanks
Inventor: GRAU EKKEHARD DIPL ING DR
IPC: F16C33/14

The forming into its intermediate shape can be done in one pressing operation, thus greatly reducing the number of operations in the flange sleeve mfr.
Patent DE-2152244-A1 (DE)
Title: Tunnel annealing oven - for continuous heat-treatment of small articles
Inventor: KOHNLE WOLFGANG
IPC: C21D1/74
Filed: 1971-10-20
Abstract: A conventional endless conveyor belt, with steeping motion drive, passes over a drive roller outside the hot zone of the plant, this hot zone being refractory lined and having a continuously flowing protective gas atmos. Within the hot zone, instead of using idler rollers, the belt passes over a curved deflector plate consisting of a plane centre section and two cylindrically curved ends each turning the belt through approx. 90 degrees. The plate has a support strip welded to its inner face at an angle and with its free edge resting in the open upper side of an angle section outside the hot zone and fixed to the frame. An external spring or a push rod in the belt return channel is used to restore the plate to its correct angle, i.e. approx. 5 degrees to the vertical, the belt being canted upwards from the loading end at that angle so that the oil quenching bath can be placed directly below the discharge chute at the top of which is a chimney through which the protective gas contaminated with oil droplets is extracted. Maintenance and adjustment of belt tension are simplified.
Patent DE-2160240-A1 (DE)
Title: Block type heat-exchanger - with differential channel arrangement and flow velocities
Inventor: LINDER HANS
IPC: F28F21/02
Filed: 1971-12-04
Abstract: At least one massive block of graphite is used in which there are two sets of channels for the two media in a heat exchange relationship, these channels being in orthogonal directions. The channels for the product medium are arranged in double parallel rows with those for the other medium in single rows between them. the flow velocity in those channels which car in single row is higher than that in the channels in twin rows. Higher thermal transfer capacity without high press. drop due to high flow velocity in the prod. medium is achieved.

Title: Flame-cutting powders contg. titanium - increase heat evolution and permit higher aluminium content in iron aluminium mixt.
Inventor: KALLENBACH RUDOLF
IPC: B23K35/22
Filed: 1973-06-08
Abstract: The powder contains 0-110% Ti metal as a mixt., alloys, or in other phases, any further ingredient is related to the Ti content or to the type of material being cut. The Ti can be used alone or in powder mixtures of T2-Fe-Al, where it permits the use of a higher Al: Fe ratio, thereby increasing the heat evolved; the higher Al content also increases silicate formation when SiO2 is present in the material being cut. Mg or its alloys can be added to the Ti mixt.

Abstract: A tool for moulding thermosets features a base plate and >=1 flexible band forming a cylindrical wall, the band comprising at least partly an electrically conducting material, being openable, and having terminals for admitting a heating current. Means are provided to adjust the band to the shape of the moulding as it changes its volume during curing. The strength of the heating current may also be varied during that stage. Close control of the hardening reaction may thus be exercised during moulding to minimise risk of stresses, cracks and voids being formed in the moulding.

Title: Security encoding communication network - uses start code to set code generators before transmission of signals
Inventor: OSTERMANN BERND DIPL-ING
IPC: H04L9/12
Filed: 1973-07-06
Abstract: The communications network (e.g. for teleprinter or telephone) has security encoders/decoders. Before transmission each encoder or code generator is set by a start code stored at each end station. Some of the stations have a given number of start codes held in special memories. Identification signal sequences are associated with each stored code and are used to select the wanted code. The advantage lies in not only allowing authorised stations to exchange coded information with one another but also with any other station that has access to the identification signals and therefore to the code being used.
